9900-431 速度控制 反向控制装置 WOODWARD

【产品详情】

9900-431 型号是由伍德沃德公司制造的 24 伏反向作用负载分配和速度控制。该型号是 2301A 系列的一部分。9900-431型号的速度和负载分配功能将由汽油或柴油发动机控制。

Woodwards 2301A 负载分配和速度控制系列 9900-431 是一种 24 伏反向控制装置，设计用于汽油或柴油发动机。在这种反向作用控制中，随着执行器的电压增加，执行器通常需要更多的燃料，而反向作用控制燃料随着电压的降低而增加。反向作用控制的外部接线与直接作用控制的外部接线没有区别。与正向作用控制不同，反向作用控制装置（例如此型号）不建议使用启动燃油限制。

重要的是要注意，9900-431 上的速度范围在出厂时设置为 2000 Hz 到 6000 Hz; 这些速度可以更改，但明智的做法是将这些设置保持在标准，以免导致超速;如果必须更改速度范围，请取下盖子并仔细确定需要打开或关闭哪个摇臂开关;对于 500-1500 Hz，打开一个摇臂开关，其余三个开关处于关闭位置。

在启动控制时，检查速度传感器至关重要。测量端子 28 和 29 处的电压;起动速度下的最低电压为 1.0 Vrms，额定速度为 30 Vrms。明智的做法是，如果您在控制器上设置的额定速度设置不能产生正确的输出，请将设置返回到控件的标准起始位置。

9900-431 型号具有单个印刷电路板和位于机箱前部的可调电位计。速度电位器将根据速度传感器频率进行设置。

使用 9900-431 型号时，环境是否有任何限制？

使用 9900-431 型号时没有环境限制，因为它额定在恶劣条件下使用。9900-431 型号具有内置保护罩，有助于保护 9900-431 装置免受射频/电磁频率、灰尘、振动和湿度的影响。有关 9900-431 型号可用于的环境条件的更多信息，请参阅 82390 伍德沃德公告。

9900-431 型号的反向操作与正向操作控制装置有何不同？

正向作用和反向作用控制之间的主要区别在于，随着执行器电压的降低，执行器将需要更多的燃料。当执行器发生电压损失时，它将充满燃料。当执行器达到满油时，它允许球头调速器进行控制，而不是关闭整个发动机。

【英文介绍】

Model 9900-431 is a 24-volt reverse-acting load distribution and speed control manufactured by Woodward. This model is part of the 2301A series. The speed and load distribution functions of the 9900-431 model will be controlled by a gasoline or diesel engine.

Woodwards 2301A Load Distribution and Speed Control Series 9900-431 is a 24-volt reverse control unit designed for use in gasoline or diesel engines. In this reverse action control, the actuator usually requires more fuel as the voltage of the actuator increases, while the reverse action control fuel increases as the voltage decreases. There is no difference between the external connection of the reverse action control and the external connection of the direct action control. Unlike forward action controls, reverse action controls (such as this model) do not recommend starting fuel restrictions.

It is important to note that the speed range on the 9900-431 is set from 2000 Hz to 6000 Hz at the factory; These speeds can be changed, but it is wise to keep these Settings to standard so as not to cause overspeed; If the speed range must be changed, remove the cover and carefully determine which rocker switch needs to be turned on or off; For 500-1500 Hz, one rocker switch is turned on and the other three switches are in the off position.

It is crucial to check the speed sensor when activating the control. Measure the voltage at terminals 28 and 29; The minimum voltage at starting speed is 1.0 Vrms and the rated speed is 30 Vrms. It is wise to return the setting to the control's standard starting position if the rated speed setting you set on the controller does not produce the correct output.

Models 9900-431 feature a single printed circuit board and an adjustable potentiometer located at the front of the case. The speed potentiometer will be set according to the speed sensor frequency.

Are there any environmental restrictions when using model 9900-431?

There are no environmental restrictions when using the 9900-431 model, as it is rated for use in harsh conditions. The 9900-431 model has a built-in protective cover that helps protect the 9900-431 unit from RF/electromagnetic frequencies, dust, vibration, and humidity. For more information about the environmental conditions in which model 9900-431 can be used, see the 82390 Woodward Bulletin.

What is the difference between reverse operation and forward operation control for model 9900-431?

The main difference between forward and reverse action control is that as the actuator voltage decreases, the actuator will require more fuel. When a voltage loss occurs in the actuator, it will be filled with fuel. When the actuator reaches full fuel, it allows the ball head governor to take control instead of shutting down the entire engine.
